117: Catheter Precision Tester

The four members of engineering senior design team 117 stand together on the third floor breezeway at the FAMU-FSU College of Engineering.

We designed the Catheter Deflection Verification System (CDVS) as a quality assurance tool to enhance the precision and reliability of catheters used in cardiac ablation procedures. Accurate energy delivery to specific heart regions is essential for successful ablation, as variability in catheter deflections can lead to incomplete lesion formation, unintended tissue damage or additional procedures. The CDVS ensures a 1:1 translation between input angles applied at the catheter handle and output angles observed at the tip. Key design components include servo motors that generate precise input angles (0°, 45° and 90°), magnetic encoders that verify these inputs and IMUs or imaging-based systems that measure the resulting output angles. 

We aim to provide an accurate, repeatable testing platform for catheter design improvement, help manufacturers meet regulatory standards and support physicians by ensuring consistent catheter performance. Its compatibility with existing catheter systems, portability and cost-effectiveness make it a practical solution for laboratory use. By bridging a critical gap in catheter testing technology, the CDVS improves procedural consistency, reduces risks and enhances patient outcomes. The system offers significant value to biomedical engineers, manufacturers and healthcare providers by ensuring catheter performance meets quality standards, ultimately elevating cardiac ablation care standards.
